At Last A Predictable Weathered Crackle Glaze.

A crackle glaze is a simple idea, they attempt to re-create the effect of old varnish that cracks and crazes over time.

A crackle glaze generally consists of a base coat and a top coat. The way they work is simple the water-based varnish dries quicker than the oil-based one, and the movement from the underlying layer, which is still drying, causes the top layer to crack. 

I have used many of the available crackle glazes in my time, oil based varnishes with a water based top coat, made from animal glue or an acrylic varnish, the oil based crackle glazes were often difficult to control owing to the temperature range they worked under, also it was difficult to control the size of the cracks, as the picture on the left shows.

On this page are some examples of weathered two part oil and water crackle glazes, some of these have had added an ageing glaze to give an older appearance to the metal leaf. Please note in all these examples and others that follow we use only imitation gold leaf, of course if you do want to use real gold leaf you can do so, you will get very much the same effects.

You can also apply a crackle glaze to a painted surface or onto wood, stone, porcelain, glass or metal, it would be wise to seal the piece with shellac.

Because the traditional oil/water glazes are sometimes difficult to get results from, due to local temp, humidity etc, I no longer sell them from this site, I had too many complaints about not getting results.

However I have shown pictures of the oil/water glaze as, when it works, it produces a nice variety of medium sized cracks.

The only crackle glaze I am prepared to call fool proof is the two part acrylic crackle glaze that I sell from here and which produces a fine network of cracks as the picture in the top right shows.

You can purchase a simple and reliable 2 part crackle glaze from the gilding supplies page.

It is normal after applying the crackle glaze, to apply an antique glaze over it in order to highlight the cracks, lets see how the antique glaze is applied.
